Everyone needs to keep their eyes protected from unsafe sunrays by using sunglasses. The glasses that are advised by opticians are ones that protect against UVB, HEV and UVA rays. You will be saving yourself from getting cancer around your eyes and cataracts.

Dark glasses are not only for fashion. They are not made to keep you from squinting when you drive or when you are outside. Glasses with lenses that block the sun from your eyes are made for your protection.

Exposing unprotected eyes to excessive amounts of ultraviolet rays over a short amount of time can cause photokeratiis, or sunburn in the eyes. This can be painful, and give you the feeling of having sand in your eyes. This is usually only temporary and hardly ever causes permanent damage to the eyes. However, long term exposure to this can be more serious. Which is why people need to be made aware of why they need to wear glasses that shade the eyes.

Scientific research has found that overexposure to UVA rays can cause cataracts and damage to your retina. Even though UVB rays have lower energy than UVA rays, over a period of time these rays can cause skin cancer around the eyes. In the short term UVB rays can cause inflammation of your cornea which causes temporary vision loss, lasting anywhere from 24 to 48 hours. This could happen because no eye protection was worn while out in the snow.

Eighty percent of exposure to the sun occurs when people are younger than age 18. Children are known to spend more time outside than adults. This is why it is very important to protect their eyes as well as your own. Glasses that block out at least ninety nine percent of harmful rays are recommended.

It does not matter if your lenses are plastic or glass. Both can be good for shading you from harmful rays. Make sure whatever ones you do buy have a UV absorption of 400nm. This means they will block one hundred percent of damaging rays.

The light that bounces off pavement or other smooth surfaces like water is called glare. Polarized lenses will cut down on glare but do little to protect your eyes. UV protection can be combined with polarized lenses so that you get both glare reduction and protection.

The color of the lens in your glasses is unrelated to the amount of UV protection they give. You can have a light amber lens and have the same UV protection as a dark grey lens. The color does matter for HEV protection though. HEV stands for high-energy visible radiation, or blue light.

{Ultraviolet light rays do have more energy than HEV rays, but HEV radiation will go deeper into the eyes and have damaging effects on your retinas. A reddish brown, bronze or copper lens is best for protection from these rays. The label on these glasses might say blue blocking. You can find glasses that will protect you from all of the harmful rays.Ultraviolet light is stronger than high-energy visible light, but the rays from the HEV light go deeper into the eye. This can cause retinal damage. Glasses that protect against this would be bronze, copper or reddish in color. The label on these might say blue blocking lenses. You can get all of the protection against UVA, UVB and HEV in one lens.

It is not hard to comprehend why everyone needs to have a pair of fashion sunglassesthat will protect from the harmful rays of the sun. All people do not need to have Hugo Boss sunglasses because not all people drive or spend a lot of time outdoors. Everyone does need to protect their eyes though.
